The reason for extracting a tooth may be all too obvious — the tooth is too decayed or damaged to attempt saving. The reason for extracting a wisdom tooth, on the other hand, may not be so apparent: from the perspective of pain or reduced function, you may not notice a thing. Our recommendation to remove a wisdom tooth is based primarily on what may be occurring out of view below the gum line and its potential threat to adjacent teeth.

Teeth grow and develop below the gum line in the jaw, and then push their way through the gums as they appear in the mouth (eruption). After a normal eruption, the enamel-covered crown is visible above the gum line; the remaining tooth root (about two-thirds of the tooth’s length) resides below the gum line. Because wisdom teeth, or third molars, erupt rather late between ages 17 and 25, they may lack the room to erupt properly due to crowding from other teeth that have already erupted. This can cause the wisdom tooth not to erupt fully through the gums, leaving the crown trapped below the gum line, a condition known as impaction. For the tooth, impaction increases the chances of infection, cyst formation and gum disease around it.

An impacted wisdom tooth can also cause problems for the adjacent teeth as well. The impacted tooth may begin to press against the roots of other teeth; the resulting pressure can damage the other roots, increasing the risk for disease or future tooth loss. A person may not even know they have this problem since there’s often little to no noticeable pain or symptoms.

It may seem counterintuitive, but the best time to remove a wisdom tooth is when it’s not causing immediate problems. There will be, however, signs found during examination (particularly x-rays or CT scan) that future problems are in the making. By extracting an impacted wisdom tooth at the appropriate time, we can avoid more serious problems in the future and improve oral health.

Teeth damaged by decay, periodontal (gum) disease or trauma are often removed (extracted) if they’re deemed beyond repair. But there’s another reason we may recommend an extraction: a tooth is causing or has the potential to cause problems for other teeth and your overall oral health.

Some of the most frequent cases of “preventive extraction” involve the third molars, or wisdom teeth, located in the very back of the mouth. They’re usually the last permanent teeth to come in, which is related to some of the problems they can cause. Because they’re trying to come in among teeth that have already erupted they don’t always erupt properly, often at abnormal angles or not fully erupting through the gums, a condition called impaction.

Impacted or misaligned wisdom teeth can put pressure on adjacent teeth and their roots, which can cause root resorption that damages the second molar. They can also increase the risk of periodontal (gum) disease in the gum tissues of the second molars, which if untreated can ultimately cause teeth and bone loss.

Because of current or possible future problems with wisdom teeth, we often consider removing them at some early point in the person’s dental development. Such a consideration shouldn’t be undertaken lightly, since wisdom teeth extraction is often complex and fraught with complications, and it usually requires a surgical procedure.

That’s why we first conduct a comprehensive examination (including x-ray or other imaging to determine exact location and possible complications) before we recommend an extraction. If after careful analysis an extraction appears to be the best course, we must then consider other factors like planned orthodontics to determine the best time for the procedure.

Once performed, a wisdom tooth extraction can resolve existing problems now and reduce the risks of gum disease or malocclusions in the future. When it comes to wisdom teeth, removing them may be in your or your family member’s best interest for optimal dental health.

“Impacted wisdom teeth.” The term alone sounds ominous. What are wisdom teeth, why do they become impacted, what is the best way to treat them? These are questions people often ask.

What are “wisdom teeth” anyway?Your third molars, located in the very back of your jaws, are your wisdom teeth. Most people have four of them.

Why is their name associated with wisdom?They usually begin to come in when a person is 17 to 25 years old, a time when he or she can be said to begin to reach an age of wisdom.

Doesn't everyone get wisdom teeth?While some people have more than four, others have fewer, and some have no wisdom teeth at all. Some people have wisdom teeth that can be seen in x-rays but do not erupt (grow up through their gums) and become visible.

What does “impacted” mean?In normal usage, the term “impact” means “influence or effect.” In dental vocabulary, it means that a tooth is affecting another tooth or a nearby structure such as gums, nerves or blood vessels. Often an impacted wisdom tooth grows sideways into an adjacent tooth instead of growing upwards to come through the gums normally. This may be caused by a lack of room in your jaw for your third molars.

What kinds of problems can impacted wisdom teeth cause?A wisdom tooth can impact the gum tissues surrounding nearby molars, leading to infection called “periodontal disease” (from the root words for “around” and “tooth.”) They can also cause root resorption in adjacent teeth, a process by which the tooth’s roots are slowly dissolved and eaten away.

What are the symptoms of impacted wisdom teeth?Sometimes impacted teeth are asymptomatic — you feel nothing, even though damage is being done to gums and teeth surrounding the wisdom teeth. That's why it's a good idea to have regular checkups even if you are feeling no pain. Other times, impacted teeth can lead to acute inflammation and infection in surrounding gum tissues that is very painful.

Should I proactively have my wisdom teeth removed if they are not giving me any trouble?
Not necessarily but your wisdom teeth need to be evaluated. Generally speaking, however, it's better to remove wisdom teeth early, before they begin to cause dental problems. By the time a wisdom tooth starts to hurt, its neighboring teeth may already be in big trouble. In addition, younger people's wisdom teeth have undeveloped roots that make them easier to remove with fewer complications.

Anytime you have a tooth that does not erupt (surface) correctly but rather stays submerged below the gum you have a problem. Sometimes this situation can cause significant pain, while other times it can be totally pain-free. When this occurs to a wisdom tooth (third molar), you have what is commonly referred to as an impacted wisdom tooth. This generally occurs when there is insufficient room in the mouth, and the wisdom tooth “impacts” or butts up against an adjacent tooth.

Third molars come in typically between the ages of 17 and 25, when a moderate amount of “wisdom” is supposedly achieved. Most people have four wisdom teeth; however, it is possible to have more or less. The key to not having issues generally depends upon one main factor: having adequate space for them to grow and erupt into proper position.

The most common consequence of having an impacted wisdom tooth is gum (periodontal) disease and damage to adjacent healthy teeth. This makes removing the impacted tooth so important. Another problem with impacted wisdom teeth is that they can affect other adjacent structures like gum, bone, nerves, blood vessels and sinuses. They can also become cystic, a condition in which the submerged tooth is surrounded by a closed sac or membrane that can cause possible infection and loss of bone.

We stress the importance of routine dental exams between the ages of 17 and 25 to catch problems with wisdom teeth before they start. The best time to remove a wisdom tooth is when it is not causing problems and the sooner and younger you are the better!

Wisdom teeth are the third set of molars that erupt in the late teens or early twenties — so-called because they come in around the age of maturity or “wisdom.” While teeth are designed to last a lifetime, wisdom teeth are often problematic requiring early removal because they frequently become impacted, meaning they are not able to erupt fully through the gums to become healthy functioning teeth. However, not all wisdom teeth need to be removed if they are fully erupted and functional.

Prevention: Having a tooth submerged below the gum, pressing on the roots of neighboring teeth can cause damage and decay even though you may not be feeling any discomfort. By the time the tooth becomes painful, significant damage may already have occurred. In addition, the ability of the body to heal following oral surgery tends to decrease with age. A recent study sponsored by the American Association of Oral and Maxillofacial Surgeons and the Oral and Maxillofacial Surgery Foundation strongly recommends that wisdom teeth be removed in young adulthood in order to prevent future problems and to ensure optimal healing.

Reasons for Removal: If your wisdom teeth are impacted against (pressing on) the roots of other teeth, damage can occur. To prevent infections, gum disease, decay, or damage to other permanent teeth, our office may recommend removal of your wisdom teeth.

What to Expect: If wisdom teeth removal is recommended, it can generally be done in the dental office as a surgical procedure with local anesthesia and conscious sedation (twilight sleep). After the surgery, you may experience some moderate discomfort and swelling depending on the degree of impaction and difficulty. Taking non-steroidal anti-inflammatory medication like ibuprofen, or prescription medication for several days after surgery will provide pain relief and control swelling.
